Denison is one of the most recognized names in hydraulic units in the world. For many years, their products were recognized by their distinctive blue color. Today, the Denison brand is part of the Parker-Hannifin family and all pumps are painted black.

This article aims to describe the main features of the vane pump technology, how it works, its advantages and disadvantages, and where it is most commonly used. Finally, we will briefly mention the Fluid-o-Tech vane pumps.

Rotary vane pumps are a type of positive displacement pump. Like all positive displacement pumps, the flow rate is always directly proportional to the speed.

Vane pumps are available with different types of vane: sliding, flexible, oscillating, rotating, and external vanes. The vane pumps are known for their dry-priming, easy maintenance, and good suction characteristics throughout the life of the pump.

A splined rotor is supported eccentrically in a cycloidal cam. The rotor sits close to the cam wall to form a crescent-shaped cavity. The rotor is sealed in the cam by two side plates. The vanes or blades fit into the rotor cavities. When the rotor rotates and fluid enters the pump, the centrifugal force, the hydraulic pressure, and/or the pushrods push the vanes towards the housing walls. The tight seal between the vanes, the rotor, the cam, and the side plate makes this technology powerful for good suction, which is common to the vane pumping principle.

The housing and cam force the fluid into the pumping chamber through holes in the cam (small red arrow on the bottom of the pump). The fluid enters the pockets created by the vanes, the rotor, the cam, and the side plate.

The rotary vane pump is very versatile and can be used in a variety of sectors and applications, from dosing to transferring and repressurizing fluids. Depending on the choice of materials, rotary vane pumps can handle a wide range of clean fluids.

Fluid-o-Tech is able to supply a wide range of rotary vane pumps covering a variety of applications in different sectors. In stainless steel, low-lead brass, technopolymer, direct coupled, magnetic or electromagnetic drive at variable speed, our pumps cover a flow rate range from 30 to 2200 l/h at pressures up to 18 bar. The built-in safety valve, available on request, limits the pressure to protect the pump and the hydraulic circuit.

The Fluid-o-Tech rotary vane pumps, WRAS or NSF certified for use with potable water, are the reference choice in the market of espresso machines and beverage dispensers for professional use.

We at Bezares are proud to summarize our successful participation at the world’s leading trade fair, Bauma 2022 were we presented our latest hydraulic developments.

In this edition, the focus was on a wide variety of future topics in the construction, building materials and mining machinery industries where Bezares presented its latest developments in hydraulic pumps and motors as well as new PTOs.

Rotary-vane pumps are positive displacement machines capable of handling lubricating and other low-viscosity fluids in low to medium volumes at low pressures and, in some applications, relatively viscous fluids. Sometimes called carbonator pumps for their use in making carbonated soft drinks, the design has traditionally been used as well in automotive applications. They have an ability to develop a good vacuum and are often used to transfer LNG as well as some solvents. Their various permutations are described here along with a discussion of their operation and common applications. For information on other pumps, please see our Pumps Buyers Guide.

These pumps combine an eccentric ring and a rotor fitted with slots. The slots hold the vanes which are capable of moving radially as the rotor turns in the ring. As the vanes revolve past the suction port, they move outward, creating a volume defined by consecutive vanes, the rotor, and the ring wall. This volume draws fluid in and is then sealed off as it moves past the suction port. On the discharge side, the combined eccentricity of ring and rotor pushes the vanes into the slots, decreasing the volume and forcing the fluid out through a discharge port. Both suction and discharge ports, or galleys, are often kidney-shaped and fill from the sides.

Vanes are often constructed from carbon graphite to minimize wear where low-lubricity fluids are handled. Centrifugal force and fluid pressure are the common means of extending the vanes out to the ring walls but positive methods of extending them such as rods are used in certain designs. The vanes themselves are able to compensate for wear and most designs allow for easy vane replacement, making sliding-vane pumps low maintenance.

Another design employs pivoting vanes which swing outward through centrifugal force to form volumes which decrease as they move past the discharge openings. External-vane pumps are also produced.

Sliding-vane pumps can be fixed-output designs or they can be manufactured with an ability to vary the eccentricity between rotor and ring. This gives variable-rate control from a constant input rpm. Pressure-compensated pumps are used in many fluid-power applications.

Like the sliding-vane pump, the flexible-vane pump relies on eccentric motion developed between a revolving rotor and a fixed ring to move fluid between suction and discharge ports. Instead of slots and rigid vanes, though, the flexible vane pump employs vanes that are molded from a flexible material which deforms as the rotor makes its circuit. This produces cavities which expand on the suction side and collapse on the discharge side. The design is useful for moving fluids that contain particles or solids as there are no critical internal clearances where such particles might lodge. Impellers are manufactured from various rubber compounds including EPDM and silicone for compatibility with a variety of products. Flexible-vane pumps are considered to be low shear.

As mentioned, soda dispensers use sliding-vane pumps to move water into pressurized CO2 tanks. Commercial espresso machines use them as well to force heated water through densely packed espresso grinds. Vane pumps are considered to be differential-pressure pumps, meaning they can pressurize a fluid entering the pump suction at higher than atmospheric pressure, as might be the case for an espresso machine that is hard-piped to the water supply. Home espresso machines typically use cheaper piston pumps designed to draw water up from built-in tanks.

Automakers use vane pumps to pressurize the low-viscosity hydraulic fluid found in power-steering systems, for which the original Vickers pump was developed. They are used both as fixed- and variable-output units in automatic transmissions. Sliding-vane pumps are best suited to low-viscosity fluids that are free of particulates. External-vane pumps are sometimes deployed to handle fluids containing solids.

Sliding-vane pumps are regularly used in refineries, terminals, etc. for pumping oils, solvents, paints, and coatings, etc. Rotary-vane technology is applied to hand-cranked pumps for manual transfer and similar operations. In recent years, micro-hydraulic systems for use in personal-assist devices have brought about the need for miniature rotary-vane pumps.

Flexible-vane pumps are heavily employed for food, beverage, and pharmaceutical services as their low-shear designs allow them to move cosmetics and similar creams without affecting their qualities or pump fluids with solids (such as yogurt) without damage. The low-shear design is also applied for marine bilge pumping and water-based glue making, for example. Flexible-vane pumps produce only low to moderate pressures, and material viscosity has a role in just how high of a pressure can be attained.

Flexible-vane pumps have very good self-priming characteristics and can be used for tank stripping and similar operations without requiring valves or hand priming. They are reversible as well, making them handy for clearing intake lines of high-viscosity products. Flexible-vane pumps offer a relatively low-cost solution for pumping solids and shear-sensitive products over other low-shear designs such as rotary-lobe pumps.

Housings can be made in stainless steel for sanitary service or bronze for marine service but ductile iron is used where possible because of its self-lubricating characteristics. The pumps are available both as close-coupled and as sealless, magnetically-coupled units. Vane pumps fall about midway between economical gear pumps and expensive piston pumps.

Finally, while rotary, positive-displacement pumps are capable of pumping water, their primary application is for oils and viscous liquids because of the need to keep rubbing surfaces lubricated and the difficulty in sealing very thin fluids. For most applications where water is the media, the centrifugal, or dynamic-displacement, pump has been the clearer choice. Vane pumps work well with low-viscosity fluids and are used to pump water to moderate pressures in several specific applications as noted here.

This article presented a brief discussion of vane pumps including the common types and how they work.

1.Cleanliness limits e.g. the level it needs from the system to work reliably and the best it will allow the system to run at, considering the duty at which it will work. Users should also consider what the consequences will be if the pump was to fail e.g. what would be the nature of the debris released during a typical failure. Does filtration need to be improved?

2.What is the minimum suction head requirement? Can pump suction conditions be improved, particularly when starting from cold? Will units operate at altitude which could increase potential issues.

3.What is the predicted life of the pump under the expected duty cycle? Remember that rated life predictions are based on normal operating conditions, which will not be the same for all installations. Have peak pressure or continuous pressure ratings been used?

7.Is planned maintenance appropriate e.g. is the fluid health checked or could it be damaged by aging or local operating conditions, therefore, reducing the life of the pump? Can the temperature of the case leakage line be monitored as a way of predicting pump damage?

10.Does the pump require a separate case leakage line? And if so what is the maximum pressure permitted. It"s always recommended to have a motor case leakage line even it the pump version doesn"t. Motor return lines are likely to exceed shaft seal limits and therefore without a drain line, high case pressures will cause seal failures or reduced life.

It is inevitable to encounter various problems in the daily use of the plunger pump oil pump. The editor summarized some of the performance doubts, faulty symptoms, and daily use abnormal problems. It is recommended to purchase a hydraulic pump for hydraulic pump manufacturers that can provide technical support and complete after -sales service. After all, the network data is scattered and cannot guarantee the accuracy of the solution.

When the spring is adjusted, the clockwise clockwise screw the flow adjustment function, and the X port is also blocked. The oil path of the port in port B must also be closed, set the pressure of the pump, then open the port B, and get oil into the system. Because the control methods of various types of plunger pumps are different, it is recommended to directly seek manufacturer"s technical support to avoid incorrect operations.

All the migrant plunger pumps must be tested by the sealing performance, efficiency, full load, speeding, noise, pressure vibration, displacement verification, etc. of the sealing performance, efficiency, full load, speed, noise, pressure vibration, displacement verification, etc. Only when the design specifications are required to enter the warehouse.

If the variable hydraulic pump is inhaled air, its external appearance may have symptoms such as noise, insufficient pressure, vibration, and hydraulic oil ascension.

The domestic hydraulic pump independently developed and manufactured by our company can seamlessly connect the imported hydraulic pump. Whether it is the appearance, structure, oil port, installation size, etc., the only performance difference is due to the differences in domestic materials, resulting in a 30%reduction in service life. However, the price of domestic hydraulic pumps is usually about 40%.

The outer oil leakage pipe should ensure that the plunger pump and the oily horse shell are filled with oil to prevent the oil from pouring the oil in the shell when the parking is higher than the shell.

(1) Oil viscosity should meet the requirements. The viscosity index of the oil is high, the viscosity is small, the viscosity index is low, and the viscosity is large. The viscosity index of the working oil of the domestic plunger pump is generally required to be above 90, and the better is more than 100.

A global leader in hydraulic pump design and manufacturing was approached by SPIROLShims regarding their use of shims. They were interested in changing their existing program with the goals of improving quality, having consistent supply and reducing overall cost.

Hydraulic pumps serve virtually every industry in manufacturing and technology applications such as chemical plants, automotive engineering, marine / offshore projects, railway engineering, civil water facilities and many other industrial applications.

The precision steel shims used in hydraulic pumps are engineered to be durable and meet extremely tight tolerances. Shims account for the variation in the pumps components for precise fit and proper bearing load.

Shims used in hydraulic pumps are manufactured to precise hardness specifications and dimensional tolerances to ensure proper long lasting functionality.

Thickness tolerance (to .0004 inch), flatness and parallelism are important for the correct shim selection based on the assembly measurements. Precise fit is needed for optimum pump functionality and durability.

The rough blanks still needed be ground to specified thickness. This was done on-site at the pump manufacturer. The grind operation was not part of their core business, was costly and slowed down the assembly lines. The hydraulic pump manufacturer wanted to remove grind operations from their facility.

The SPIROL Shims sales engineer worked closely with the pump manufacturer to determine the part"s requirements, program scope and the goals of improving quality and availability while reducing overall program costs.  After careful review and project development, SPIROL Shims was able to offer a program that addressed all of their goals.

The SPIROL proposal for the large shim program allows the pump manufacturer to focus on its core business of hydraulic pump production and not managing a time consuming shim program.

In summary, SPIROL Shims is now producing the entire package of shims for the hydraulic pump manufacturer. The shims are manufactured as complete parts with superior quality, improved availability and at a significant costs savings.

Multiple end-user industries rely on hydraulic gear pumps to attain operational efficiency. In case of applications involving highly corrosive and reactive fluids, wherein centrifugal pumps don’t fill the bill, hydraulic gear pumps are witnessing extensive demand.

However, lower replacement rates and extension of component lifecycle via repair & maintenance are likely to impede the growth of hydraulic gear pump market. New technologies introduced in the hydraulic gear pumps provide immense scope for repairs instead if replacements, creating challenges vis-à-vis demand for new hydraulic gear pumps.

Hydraulic gear pumps find extensive adoption in the building & construction industry. Flourishing building & construction activities, across both developed and developing economies, are foreseen to generate substantial demand for high-quality equipment. This, in turn, is creating prime opportunities for the manufacturers of hydraulic gear pumps in terms of volume sales.

Also, a renewed focus on infrastructure development remains a key sales influencer of hydraulic gear pumps. In addition, rapid development of commercial spaces as well as residential spaces is estimated to provide the much-needed fillip to sales of hydraulic gear pumps.

Western Europe remains a highly lucrative region for the manufacturers of high gear pumps and is estimated to account for a substantial market share over the forecast period, on account of robust demand from heavy duty segment.

Moreover, widespread presence of prominent hydraulic gear pump manufacturers, such as Bosch Rexroth AG, Linde Hydraulics GmbH & Co. KG, Eaton Technologies, Kawasaki Heavy Industries Ltd., Marzocchi Pompe, Gemma Automotive, Parker Hannifin Corporation, and others, makes this region highly- remunerative among all other regions.

Key manufacturers of hydraulic gear pumps are focusing on long-term supply contracts and launch of new products for solidifying their foothold in the global market space.

For instance, Haldex Hydraulics Systems launched a new and exclusive mobile hydraulic gear pump meant for reducing noise levels by up to ten dB(A) or 80% in case of low-speed applications, notably in forklifts and warehouse trucks. The development of this pump was a collaborative effort of the company and the University of Dresden, Germany.

Moreover, manufacturers of hydraulic gear pumps maintain a comprehensive stock holding of spares, which helps them to offer additional value to their customers. Manufacturers are also focusing on offering custom hydraulic pump designs and manufacturing to serve diverse customer requirements.

A hydraulic hand pump is a simple, yet essential piece of equipment used in a variety of industries. They are vital for many force applications – especially in construction, manufacturing, and maintenance operations.

However, with so many different models on the market, it can be difficult to know which is best suited to your type of work. This guide will help you understand the different pump types and their features.

Before you go ahead and buy a hydraulic hand pump, it’s important to do your research and understand their differences. With so many to choose from, you will want to compare features and prices. It is also a good idea to assess the quality of the product and if it’s made by a reputable manufacturer.

A hydraulic hand pump does a simple job, which is to deliver pressurized hydraulic flow to a tool and then return it back to the pump reservoir. But that doesn’t mean you should take shortcuts and opt for the first one that appears in your internet search results. There are a few simple but important considerations to take on board that will steer you towards the right product.

When you are choosing a hydraulic hand pump, it is important to prioritize quality over price. A high-quality Enerpac pump will last longer and be more reliable than a cheaper model. You will save money in the long run as you won’t need to replace it for many years.

With each stroke of the handle on a single-speed hydraulic pump, hydraulic oil is drawn from the pump reservoir towards the tool by the same amount. For many applications, this simpler and lower-cost option is fine. But for projects needing greater flow, for example when oil is to be pumped to a large hydraulic cylinder (or multiple cylinders), a single-speed pump can be hard work.

The alternative is a 2 stage hydraulic pump (2 speed), which has the added advantage of delivering high flow at lower working pressures. This gets you faster to the point where the real work begins. It then automatically delivers low flow at high pressure just at the time when you need more control. Compared to a single-speed pump, some two-speed types can reduce the number of handle strokes by as much as 78%! For a more in-depth comparison read our other blog post.

Hydraulic hand pumps are available in a wide range of oil capacities. A small model typically has a usable capacity of around 20 in3 (327 cm3), but there are some with as much as 453 in3 (7423 cm3). A larger reservoir will give you more options but will obviously make the pump much heavier, so think about how much oil is really needed for the applications you intend to carry out.

Most Enerpac Hydraulic Hand Pumps can withstand pressures up to 10,000 psi (700 bar), but this isn’t always necessary. For lower working pressures up to 5,000 psi (350 bar) the P18 is a cost-effective single-speed option. However, if you need a 2 stage hydraulic pump go for the P1425000.

When it comes to the materials used for the main body of the pump, you have the choice of steel or glass-filled nylon. There’s plenty of configurations available in both types, so it really comes down to your personal preferences, weight, and the working environment. Metal-bodied pumps are the traditional tried and tested option that offer reassurance to many people. However, glass-filled nylon reservoirs are also incredibly durable, and these offer an unrivalled combination of strength, weight, and resistance to corrosion. A glass-filled nylon pump will be a few pounds lighter than steel equivalents.

A double-acting cylinder gives you a faster and more controlled plunger retraction, but you will need a pump designed specifically for this purpose. Take a look at the P842, P84, and P464 models.

Safety should always be the number one concern, so choosing a good quality pump from a reputable manufacturer is an essential first step. Some features and tips relating to safety include;

When working in extreme environments such as the oil & gas, or petrochemical industries, a hydraulic pump may be exposed to corrosive substances and extreme temperatures. For these situations consider pumps with corrosion-resistant materials such as stainless steel, nickel-plated valves and cylinders, anodization, and plastic-encapsulated metals. Viton® Seals will also offer heat and chemical resistance.

Would a foot pump suit you better? If crouching to activate your hand pump is an issue, or if you want to keep your hands free then a foot pump could be a good alternative option. Look at the P392FP which is a 2 stage foot pump with a robust steel frame.

For ad-hoc projects, a hand pump is likely to be the right choice. But for frequent and repetitive projects – and especially those with multiple cylinders a powered pump could be much better for you. Plug in electric and compressed air hydraulic pumps are common. For remote locations without mains power or a compressed airline the choices are battery and gasoline-driven pumps.

If your work involves using hydraulic cylinders buying a cylinder and pump set is a quick and easy way to get what you need, without the hassle of buying components separately. A set typically includes a single-acting hydraulic cylinder (aka a jack or ram), a two-speed pump, a 6-foot hose, calibrated gauge, and a gauge adaptor. Cylinder capacities vary from 5 to 100 tons and the pump options include hand or foot-operated models.
